Releases · etcd-io/etcd-operator

The etcd-operator working group announces the release of version 0.2 of the operator. This version adds several production requirements, allowing some early adopter users to deploy it in their environments. The major features of this release are:

Certificate Management

Version 0.2 manages and installs certificates for client and intermember networking. We support an Auto Provider, suggested for development and testing purposes, and Cert-Manager suggested for production use. If TLS is enabled and no provider is specified, it defaults to Auto Provider. Other certificate plugins can be added. Arka Saha, Gurav Dasson

etcd Upgrades

Supports upgrading the etcd cluster between patch releases (e.g. 3.6.8 to 3.6.9), or over one minor update (e.g. 3.5.27 to 3.6.8). Validates that upgrades using the official etcd images adhere to upgradability rules. Lubomir Ivanov

E2E testing

We integrated gofail with our E2E testing suite and added many additional test cases. Abdur Rehman, Wenxue Zhao, Arka Saha, Nont, Hamzenium

As of 0.2, users may do all of the following:

create clusters with TLS-secured networking
increase or decrease the number of members in the cluster
upgrade clusters

Please look at our installation instructions and give the etcd operator a try today.
